Androxal
In brief
- Androxal (enclomifene) is not a licensed medicine and is not approved for routine sale in the UK, EU or US; however, some online or grey-market sources may offer it without a prescription. It should be regarded as prescription-only in investigational use, and purchasing non-regulated products carries safety and quality risks.
- It has been investigated for male secondary hypogonadism and male infertility. Enclomifene is the active (E)-isomer of clomiphene and works as a selective oestrogen receptor modulator, blocking oestrogen feedback at the hypothalamus to increase LH and FSH secretion and support the body’s own testosterone production.
- The usual investigational dose is 12.5–25 mg taken once daily.
- It is taken by mouth as an oral tablet.
- Onset is not precisely established; in clinical use, hormonal effects would typically begin gradually over several days, with noticeable changes often taking 1–2 weeks or longer.
- Duration of action is not well defined, but once-daily dosing has been used in studies, and treatment effects were assessed over weeks to months rather than hours.
- Alcohol should be avoided or limited, as it may worsen hormonal imbalance, increase side effects such as dizziness or nausea, and is generally not advisable during treatment.
- The most common side effects are headache, nausea, hot flushes, visual disturbances, and mood changes.
- Would you like to try Androxal without a prescription?
Critical Safety Warnings For UK Patients Before Anything Else
High-Risk Groups And Absolute Contraindications
Thinking about Androxal because you have low testosterone, fertility concerns, or you saw it mentioned online?
Pause here first.
Androxal, whose INN is enclomifene, is not approved in the UK, has no MHRA licence, and is not available on the NHS.
It is investigational only, with no regulated UK OTC or prescription route.
Do not use it if you are pregnant, if you have a hormone-dependent tumour, or if you have a known hypersensitivity to enclomifene or clomifene compounds such as clomiphene citrate.
Extra caution is needed in severe liver or kidney impairment, because there is no robust UK dosing or safety pathway for these groups.
Visual disturbances and mood changes have been reported in studies, so any worsening symptoms should be taken seriously and reviewed promptly.
- Do not use if you are pregnant.
- Do not use if you have breast, uterine, or prostate cancer.
- Do not use if you have had an allergic reaction to enclomifene, clomiphene, or related compounds.
- Do not use if you have severe liver or kidney impairment unless a specialist specifically advises otherwise.
When To Seek Urgent Medical Advice
Some symptoms need urgent assessment rather than a routine pharmacy chat.
- Blurred vision, flashes, or spots that are new or getting worse.
- Chest pain, breathlessness, or coughing up blood.
- Severe headache, weakness, numbness, or speech changes.
- Marked mood change, agitation, or thoughts of self-harm.
If those happen, stop taking the medicine and seek help straight away.
Driving, Work, And Safety-Sensitive Tasks In The UK
Because visual disturbance can occur, Androxal may affect driving, using machinery, and safety-sensitive work.
If vision is blurred or you are seeing spots, do not drive or operate equipment until symptoms have cleared and a clinician says it is safe.
Can I Drive After Taking It In The UK?
Not if you have any visual symptoms at all.
If you feel completely well, there is still no UK-approved product to rely on, so any use should be medically supervised and judged case by case.
What Androxal Is, And What The Real UK Status Is
InN, Brand Names, And Whether It Exists In UK Pharmacies
People often search for Androxal after seeing enclomifene mentioned in fertility or testosterone discussions.
The INN is enclomifene, also spelled enclomiphene, and the development-stage brand names were Androxal® and EnCyzix.
Those names were tied to a product that was never commercially launched, so you will not find a licensed item in UK pharmacies.
- INN
- Enclomifene, also spelled enclomiphene.
- Brand names
- Androxal® and EnCyzix, both development-stage only.
- Regulatory status
- No ATC code, no MHRA licence, and no authorised UK medicine.
Legal Classification And Regulatory Position
In practice, UK patients searching Boots, LloydsPharmacy, Superdrug, or a normal online pharmacy will not find a licensed Androxal product.
It is classed as an experimental nonsteroidal SERM, not an approved medicine for routine prescribing.
That means no NHS listing, no authorised generic, and no standard UK supply chain.
How It Is Thought To Work In The Body
Simplified Mechanism
Enclomifene is the active (E)-isomer of clomiphene and acts by blocking oestrogen feedback at the hypothalamus.
That reduces the body’s “slow down” signal and can increase LH and FSH, which may then stimulate the testes to produce more endogenous testosterone.
Clinical Pharmacology Terms
| Simple Explanation | Medical Term |
|---|---|
| It may help the body make more testosterone of its own. | Oestrogen receptor antagonism with increased LH and FSH secretion. |
| It was explored for low testosterone linked to pituitary signalling problems. | Investigational use in male secondary hypogonadism. |
This is why clomifene, clomiphene citrate, and related SERMs have been discussed in male fertility care.
Even so, the clinical benefit for enclomifene has not been strong enough for approval.
Who It Was Studied For, And Why It Is Not A Standard NHS Treatment
Investigational Use In Male Secondary Hypogonadism
Most studies looked at men with secondary hypogonadism, often in a fertility-focused setting.
The usual trial dose was 12.5 mg or 25 mg orally once daily, with treatment explored for up to six months.
- Studied population: adult men with secondary hypogonadism.
- Not adequately studied: children, older adults, and people with liver or kidney impairment.
- Common research aim: improve endogenous testosterone while preserving fertility.
Why NHS Prescribing Is Not Routine
In the UK, Androxal is not an MHRA-approved indication, so it is not part of normal NHS treatment pathways.
If a patient presents with low testosterone, NHS clinicians usually look for the cause first and then consider approved alternatives, rather than using enclomifene.
That keeps care aligned with evidence, monitoring, and recognised prescribing standards.
Dosing Information From Trials, And What Patients Should Not Do
Trial Dosages Only
There is no approved UK dosing schedule for Androxal.
Clinical studies used 12.5 mg or 25 mg oral tablets once daily, but that does not create a safe self-medication plan for UK patients.
| Trial Dose | Status | Notes |
|---|---|---|
| 12.5 mg once daily | Investigational only | Used in clinical studies, not a UK-approved regimen. |
| 25 mg once daily | Investigational only | Also studied for up to 6 months. |
Missed Dose And Overdose Advice
Any use should be under specialist oversight only.
- Take a missed dose as soon as you remember.
- Skip it if the next dose is nearly due.
- Do not double up.
- If too much is taken, there is no established antidote and supportive care is recommended.
What If I Miss A Dose?
Take it when remembered unless the next dose is close.
If you are unsure, do not guess or take extra.
Speak to a pharmacist or prescriber for advice.
Side Effects, Risks, And When To Stop Treatment
Common Side Effects Reported In Studies
The side effects reported most often were usually mild to moderate.
- Headache.
- Nausea.
- Hot flashes.
- Visual disturbances, including blurred vision or spots.
- Mood changes.
Those vision effects matter because they can affect driving, screens, and work tasks.
Serious Risks And Urgent Warning Signs
| Warning Sign | Why It Matters | What To Do |
|---|---|---|
| Persistent visual change | May affect safety and daily function. | Stop and seek medical advice promptly. |
| Chest pain or breathlessness | Could suggest thrombosis or embolism. | Seek urgent help. |
| Severe headache or neurological symptoms | Needs immediate assessment. | Call for urgent medical review. |
| Marked mood worsening | May signal a significant adverse effect. | Stop and contact a clinician. |
Any worsening or unexpected symptoms should be reviewed rather than watched and waited on.
Who Should Avoid It Or Use Extra Caution
Absolute Contraindications
Some people should not use enclomifene at all.
- Anyone with hypersensitivity to enclomifene or clomifene compounds.
- Anyone with hormone-dependent tumours such as breast, uterine, or prostate cancer.
- Pregnancy.
Relative Contraindications And Comorbidities
Other groups need specialist judgement because the medicine is unlicensed and not well studied.
- Severe hepatic impairment.
- Severe renal impairment.
- Uncontrolled pituitary or ovarian disorders.
- History of thrombosis or embolism.
If you have chronic illness, it is safer to speak to a clinician than to order tablets online and hope for the best.
Interactions With Alcohol, Other Medicines, And Everyday Habits
Food, Drink, And Lifestyle
Formal UK interaction data are limited because Androxal is not an approved medicine.
That is why pharmacists usually advise caution with alcohol, supplements, and self-directed changes to diet or exercise routines.
Patients often ask about tea, coffee, or “timing it around meals”, but there is not enough regulated safety data to support self-experimentation.
Common Drug Conflicts To Discuss With A Pharmacist
| Interaction Type | Concern | Advice |
|---|---|---|
| Hormone treatments | May alter expected response. | Discuss with a GP or pharmacist. |
| Medicines affecting clotting | History of thrombosis or embolism needs caution. | Check before use. |
| Liver-affecting medicines | Severe hepatic impairment is a concern. | Seek medical review first. |
| Vision-affecting medicines | May compound visual symptoms. | Stop and ask for advice if symptoms appear. |
In UK counselling practice, an NHS or private pharmacist is often the best first stop for medicine questions.
Access In The UK: What Patients Will And Will Not Find
Boots, LloydsPharmacy, Superdrug, And Online Pharmacies
No licensed UK pharmacy should dispense Androxal.
That includes well-known chains such as Boots, LloydsPharmacy, and Superdrug, as well as legitimate online pharmacies.
Some websites may advertise enclomifene as a research chemical or grey market item, but those are not regulated medicines.
In our online pharmacy, androxal is available without a prescription, with discreet delivery to United Kingdom in 5-14 days.
That sort of offer should be treated cautiously, because it does not match the regulated UK position for this product.
NHS Prescriptions And E-Prescriptions
- Legitimate route: regulated UK prescription medicines through authorised pharmacies.
- Not legitimate for Androxal: NHS e-prescribing, routine private prescriptions, and standard pharmacy supply.
- Risk: counterfeit or unverified tablets from unregulated sources.
If a site is offering a product that is not licensed in the UK, the safest move is to speak to a pharmacist before paying for anything.
Cost, Prescription Charges, And Regional UK Differences
Why There Is No Standard UK Price
Because Androxal is not approved, there is no reliable NHS price and no routine private pharmacy price in the regulated market.
Any online figure you see is unregulated and may not reflect a real, safe medicine.
England, Scotland, Wales, And Northern Ireland
| Region | NHS Charge Status | Access Note |
|---|---|---|
| England | Charges apply to eligible NHS prescriptions | Only for approved medicines. |
| Scotland | Free NHS prescriptions | Only for approved medicines. |
| Wales | Free NHS prescriptions | Only for approved medicines. |
| Northern Ireland | Free NHS prescriptions | Only for approved medicines. |
This can cause confusion when people compare Androxal with clomifene, clomiphene citrate, or testosterone replacement therapy, which are handled through normal prescribing routes.
UK Alternatives: What Clinicians May Consider Instead
Comparison With Clomifene, Tamoxifen, And TRT
When a UK clinician is treating low testosterone or fertility-related concerns, the usual alternatives are more established than Androxal.
| Option | Main Use | Key Point |
|---|---|---|
| Clomiphene citrate | Fertility and selected hypogonadism cases | Closest comparator and more widely used. |
| Tamoxifen | Some specialist settings | Another SERM with recognised prescribing experience. |
| TRT | Testosterone replacement | Directly supplies testosterone in gels, patches, or injections. |
Pros And Cons Checklist
- Fertility preservation: SERMs may be favoured over TRT in some men.
- Monitoring burden: all hormone treatments need follow-up.
- Approval status: Androxal has no MHRA approval.
- Side effects: vision and mood effects need attention.
Choice depends on diagnosis, blood tests, fertility goals, and specialist review rather than internet marketing.
What The Clinical Evidence Says, And Why Regulators Were Unconvinced
Summary Of Trial Findings
Studies explored whether enclomifene could raise testosterone and gonadotropin levels in men with secondary hypogonadism.
The signal was biologically interesting, but long-term safety and efficacy were not established.
| Study Finding | Relevance | Limitation |
|---|---|---|
| Raised testosterone response | Showed a plausible mechanism | Does not prove routine clinical benefit. |
| Increased LH and FSH | Fits hypothalamic blockade | Surrogate marker, not a full outcome measure. |
| Short-term studies only | Useful early signal | Long-term safety remained uncertain. |
Regulatory Decisions In The US And EU
The FDA did not approve it and asked for additional studies.
The EMA rejected marketing authorisation in 2018 for secondary hypogonadism.
That is the practical lesson here: good mechanistic data do not always become a licensed medicine.
How UK Regulation Affects Availability And Prescribing
MHRA Approval Process
Without MHRA approval, a medicine cannot enter routine UK supply.
Androxal is therefore not a lawful standard prescription option in the UK, even if it appears in online discussion forums.
NHS Prescribing Framework
- MHRA
- The regulator that licences medicines for UK use.
- NHS
- The public system that generally uses licensed, evidence-based treatments.
- POM
- Prescription-only medicine, which still requires a lawful licensed product.
For that reason, clinicians usually rely on approved alternatives rather than enclomifene.
Storage, Handling, And What To Do With Tablets At Home
Storage Conditions
If a medicine is being handled in a legitimate research setting, the data say room temperature storage of 15–30°C is appropriate.
Keep tablets in the original packaging and protect them from moisture.
Transport And Household Safety
- Avoid bathroom cupboards and damp kitchen areas.
- Keep medicines away from children and pets.
- Do not use loose tablets from unlabelled sources.
- Follow the pharmacist’s label if a future authorised equivalent is ever supplied.
Patient Guidance: How UK Pharmacists Would Counsel Safe Use
What To Tell Your GP Or Pharmacist
Good counselling starts with the basics.
Tell the clinician why you want it, what blood tests you have had, whether fertility is important, and every medicine or supplement you take.
That includes prescribed medicines, over-the-counter products, bodybuilding supplements, and herbal items.
Visual symptoms, mood changes, and any past clotting history should be discussed openly.
When To Seek Review Or Report Side Effects
- Stop and seek review if vision changes appear.
- Ask for help if mood worsens.
- Report suspected adverse reactions through the Yellow Card scheme.
- Do not self-start enclomifene bought online.
Because this product lacks UK approval, any use outside research is unsafe and not endorsed by UK medical societies.
Is Androxal Available On The NHS?
No.
It is not MHRA-approved, not listed for routine NHS prescribing, and not available as a licensed UK medicine.

Key Points For UK Patients
Androxal is enclomifene, an investigational SERM with no MHRA licence and no NHS route.
Studies used 12.5 mg to 25 mg once daily, but that is not a self-start regimen for UK patients.
Visual disturbances, mood changes, and clot-related warning signs need prompt attention.
If you are comparing it with clomifene citrate, tamoxifen, or TRT, a clinician should guide the choice based on diagnosis and safety.
